TYPE-WRITI NG MACHINE.

SPECIFICATION forming part of Letters Patent No. 470,172, dated March 8,1892.

Application filed September 3, 1891. Serial No. 404,590. (No model.)

1'0 all whom it may concern.-

Be it known that I, WALTER J. BARRON, a citizen of the United States,and a resident of Brooklyn, in the county of Kings and State of NewYork, have invented certain new and useful Improvements in Type-\VritingMachines, of which the following is a specification.

My invention relates, first, to the paperfeed-ing devices, and,secondly, to the ribbonfeeding devices; and it consists in the featuresof construction and combinations of devices, hereinafter more fullydescribed, and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a front view of a type-writingmachine embodying my improvements, the keyboard being removed to afforda viewof the construction and arrangement of the devices at the lowerrear portion of the machine which form part of the ribbon-movingmechanism, and the paper-carriage being turned up to afford a view ofthe paper-feeding devices. Fig. 2 is a side elevation of the machinewith the keyboard added and the paper-carriage down in working position,and with a portion of the frame-work at the rear of the machine brokenaway to show the arrangement of the ribbonfeeding devices, and with theknob or handwheel at the left-hand end of the pressureroller shaftomitted to avoid complication of the view. carriage with the pressure orfeeding roller out of engagement with the platen. Fig. 4 is a face viewof one of the driving-pawls of the ribbon-spool ratchet-wheel. Fig. 5 isa diagram to illustrate the movements of the ribbon and the manner inwhich the type strike the same. Fig. 6 is a partial front view similarto Fig. 1, but exhibiting the devices for feeding the ribbonlongitudinally, as arranged to operate on the downward movement of thedriving-pawlin lieu of the upward movement, as in the arrangement shownat Fig. 1.; and Fig. 7 is a diagram to show the movement of the ribbonand the manner in which the type strike the same when the ribbon is fedin accordance with the plan shown at Fig. 6. 1

In the various views the same part will be found designated by the samenumeral of reference.

The machine illustrated will be recognized as that known as theCaligraph, to which Fig. 3 is a side view of the paper-,

my ribbon-feeding improvements are more especially adapted.

1 designates the frame-work of the machine 2, the type-ring; 3, thecarriage guide-bar; 4, a yoke adapted to slide on said guide-bar andconnected with the rear rod 5 of the papercarriage. In the side bars 6and 7 of the paper-carriage is mounted to rotate the usual cylindricalpaper-platen 8, having at one end a ratchet-wheel 9, adapted to aline-space leverand platen-check, (not shown,) and having also at theend of its axle a hand-wheel 10, by which the platen may be turned. Thefront rod 11 of the carriage is provided, as usual, with ananti-friction roller 12, which travels on a track or way 13, supportedon pillars 14 at each end and secured in place by long vertical screwspassing through the track and pillars and entering tapped holes in thetypering or top plate 2. To the front side of the track or way isattached the usual machinescale 15, with which co-operatesa pointer 16,arranged centrally of the front rod of the paper-carriage. 17 is apaper-guide for the mid dle portion of the sheets, the said guide,pointer, and wheel all being mounted on a bracket 18, attached byascrew19 to the front carriage-rod.

The rear carriage-rod near each end is provided with a bracket 20,supporting an arm 21, which is extended and curved to pass under theplaten and serve as an end paperguide 22. Upon each of said arms isaffixed a bracket 23 to support the shaft'or axle 24E of a pressure orfeeding roller 25, which preferably is provided at each end with aknurled hand-wheel 26. Near each end of said shaft is formed or provideda cam or wedge 27 to co-operate with depending arms 28, screwed at theirupper ends to the end bars of the paper-carriage. Each cam or wedge istapered in the same direct-ion, so that when the shaft- 24. and roller25 are moved endwise toward the left the depending arms 28 may both acton said cams or wedges to simultaneously force both ends of the shaft,and hence the pressure-roller, outwardly or away from the paper-platen,as shown at Fig. 3. The pressure-roller is made Slightly shorter thanthe distance between the supporting-brackets 23, in order that theendwise movement referred to may be accomplished. The bevel or taper ofthe wedges is such that the roller may be moved out of contact with theplaten a sufficient distance to enable the paper used to be freelyinserted or removed without operating or disconnecting the line-spacingdevices or disconnecting the usual platen -checl and without rotatingthe platen. By this construction the paper may be more speedily insertedand removed. By constructing and arranging the feed-roller so that itmay have an endwise movement provision is also made for feeding thepaper laterally either to the right or left, so that any omittedcharacterin a line may be printed in its exact place and so that at theend of the line one or more extra letters may be added, if necessary ordesired.

In correcting type-written matter after the sheet has once beenwithdrawn from the platen it is quite diflicult to so reinsert the sheetas that the blank space which is to be supplied with a character willcome exactly centrally of the prii'iting-point, or, in other words, itis almost impossible to bring the line of print into exact registeragain with the usual scale 29 on the under side of the platen, and ifthis be not done the printing of the character inserted must take placenearer one letter than the other, instead of midway between the twoadjacent letters of the word, which gives to the work an appearance ofimproper letter-spacing of the carriage and is unsightly.

In the machine illustrated at Fig. 1 it will be observed that the shaftof the pressureroller may be moved endwise about a letterspaoe distancebefore the depending arms 28 can act upon the cams to throw off thepressure-roller, and this mevement is provided to enable the lateralfeed of the paper.

It will be understood that the pressureroller operates to hold thepaperfirmly against the platen and at all times, excepting when the camsare under or in line with the depending arms 28, and hence that if thepressure-roller be moved endwise toward the left, Fig. 1, the paper willbe carried with it by reason of the frictional contact of said rollerwith the paper. In feeding the paper laterally the pressure-rollershould not be moved endwise its full distance or far enough to allow thecams to be acted upon by the depending arms 28. With each such endwisemovement of the roller the paper is moved laterally a letter-spacedistance; but this distance may be lessened, of course, by decreasingthe extent of the endwise movement of the pressure-roller, and the papermay therefore be moved laterally only very slightly, instead of a fullletter-space distance, at one movement of the pressure -roller, inaccordance with the exi encies of the case. If it be dea I a u sired tomove the paper sldewlse a distance greater than that of a letter-space,the papermay be held by the thumb at one edge after the first endwisemovement of the roller, while the roller alone is returned to its firstposition, and the thumb may thenbe removed and the roller moved endwiseagain to carry the paper still farther laterally. In this way the papermay be moved any number of letter-spaces or fractions thereof laterallyby the pressure-roller within the limits of the carriage, and for thisreason several additional letters or an extra word may be added to theline of printing.

By prolonging the axis of the pressure-roller and providing afinger-piece, as 26, the said roller may not only be moved endwise, butmay be also rotated, which latter is a great desideratum, since byturning said roller the reinserted sheet may be fed in line-spacedirection to any extent without rotating the platen or actuating theusualline-spacing devices, andhence the line to be printed can bebrought to register with the printing-point with great nicety andwithout pulling upon the paper with the hands, as usual heretofore, atthe risk of tearing or soiling the sheet.

Centrally of the machine and extending from the front to the back is arod or shaft 30, about which is coiled a carriage-driving spring 31.,and at the rear end of said rod or shaft is connected an arm 32, whichis connected with the paper-carriage, as in the caligraph. Beneath thekey-levers 33 is a universal bar-frame 34, pivoted at 35 and providedwith an arm 36,carrying a feed-dog 37, adapted to engage with thefeed-racks 38 and 39 on the carriage, as usual. At the left-hand side ofthe machine is a ribbon-spool shaft 40, mounted in bearings4l andprovided with a crank and handle 42. Upon said shaft is splined aribbon-spool 43, which is arranged within a frame or carrier 44, adaptedto slide longitudinally on said shaft and carry with it saidribbon-spool. At the right-hand side of the machine another ribbon-spoolshaft 45 is mounted in bearings 46, and upon said shaft is splined aribbon-spool 4:7 and arranged another ribbon-spool frame or carrier 48.

At the base of the machine and near the rear end is arranged atransverse rock-shaft 49, which is provided at each end, exteriorly ofthe side frames of the machine, with a rocker-arm 50, the upper end ofwhich engages a ribbon-spool carrier 48. At the lefthand side of themachine the said rock-shaft is provided with a horizontal arm orextension 51, which projects rearwardly and beneath the outer arm of alever 52, pivoted horizontally at 53 in the frame-work. The inner arm ofsaid lever rests upon a lug or projection 54., extending laterally fromthe spring-actuated driving rod or shaft 30.

At the left-hand side of the'machine is a coiled spring 55, one end ofwhich is attached to the frame-work and the other end to the left-handrocker-arm 50. By this construction and arrangement the ribbon 56 isgiven a transverse or lateral movement toward the front of the machineduring the travel of the carriage to the left and a. similar movementtoward the rear of the machine during the ICC travel of the carriage tothe right for the beginning of a new line.

At Figs. 1 and 2 the carriage is supposed to be at the extreme right andthe ribbon-spools and ribbon at the end of their rearward movements.

If the machine be operated, the paper-carriage will be fed step by steptoward the left of the machine under the influence of the driving-spring31, rod 30, arm 32, and escapement devices, as usual. As the carriagetravels in this direction, the lug or projection 54 moves slowly in thedirection of the arrow at Fig. 1 and allows the inner arm of the lever52 to descend, the outer arm of said lever to rise, through the upwardmovement of the arm 51, and the spring 55 to rock the shaft 49 and arms50 and move the ribbon-spool carriers and ribbon spools and ribbontoward the front of the machine, The movements of the parts are all sotimed that when the carriage has traveled from right to left its wholedistance the ribbon is moved laterally toward the front substantiallyits wholewidth, and by means of the spring 55, which is expanded whenthe carriage is moved to the right, and

which retracts and exerts a pull when the carriagetravels to the left,and the .lug 54 moves down in the direction of the arrow. When thecarriage is returned by hand to the right-hand side of the machine forthe commencement of a new line, the lug or projection 54 is turned inthe opposite direction and lifts the inner end of the lever 52 andthrows down its outer end and causes it to depress therearwardly-projecting horizontal arm of the rock-shaft, so as to vibratethe rocker-arm rearwardlyagainst the tension of the spring 55 and causethe ribbon-spool carriers and ribbon-spools and ribbon to move towardthe rear of the machine to the position illustrated at Figs. 1 and 2.During the return of the carriage from left to right the ribbon is movedlengthwise or partially wound from one spool onto another, preferably adistance about equal to the width of a type.

At the front end of the shaft 40 is secured a ratchet-wheel 57, adaptedto be acted upon by a dog or tooth 58, having a slot 59 to provide forexact adjustment and attached by a screw 60 to a vertically-arranged rod61, attached at its lower end by a screw 62 to a forwardly-projectingrocker-arm 63, fast on the rock-shaft 49. The upper end of said rod 61preferably projects through an elongated hole in the top plate 2, andsaid rod is provided with a spring 64, attached to said top plate forthe purpose of keeping the driving pawl or tooth 58 in engagement withthe ratchetwheel 57 when it may be desired to have said ratchet-wheelturn.

At 65 in the frame-work is pivoted a dog 66, having a dependingextension 67 of sufficient weight to keep said dog in engagement withthe ratchet-wheel 57 when such engagement may bedesired.

At the right-hand side of the machine the spool-shaft 45 is providedwith a ratchetwheel 68, adapted to be engaged byadriving pawl or tooth69 similar in construction to the one at the other side of the machineand mounted on a vertically-arranged rod 7 O, attached at its lower endto a rocker-arm 71 on the rock-shaft 49. The upper end of said rod 7 Ois also preferably made to pass through an elongated hole in the topplate 2, and said rod is likewise provided with a spring 72, adapted tokeep said pawl 69 in engagement with said ratchet-wheel 68, whendesired. At 73 in the frame-work is pivoted a dog 74, adapted to engagewith said ratchet-wheel 68 and provided with a depending extension 75 ofgreater weight than said dog, in order that the latter may standnormally in engagement with said ratchet-wheel. i

Across the machine, just back of the keyboard and mounted to turn inbearings in the frame-work, is arranged a rock-shaft 7 6, which at oneend is provided with a crank 77. and which near its left-hand end isprovided with a finger 78 and near its right-hand end with a finger 79.The Said fingers 78 and 79 are beveled or tapered at their ends inopposite directions to have a wedging effect, and saidfingers areprovided for the purpose of alternately disengaging the pawls and dogsof the ratchet-wheels when'it maybe desired to reverse the direction ofthe longitudinal travel of the inking-ribbon. I 1 The operation offeeding the ribbon longitudinally is as follows: At Fig. l-thedrivingpawl is shown as in engagement with the ratchet-wheel 68. As thecarriage moves step by step to the left the said pawl gradually descendson account of the downward movement of the rod and rocker-arm 71; butsaid pawl is kept in contact with its ratchetwheel by means of thespring 72. On the return of the carriage toward the right said pawl 69,through the rise of the rocker-arm 71 and rod 70, is elevated, and byreason of itsengagement with the ratchet-wheel 68 operates to turn theribbon-spool 47 in the direction of the arrow and wind a small portionof the ribbon upon said spool. During the descent of the pawl 69 theribbon is not moved lengthwise and the spool 47 is held against backwardrotation by reason of the engagement of the holding-dog 34 andratchetwheel 68. WVhen the ribbon may have been thus wholly wound fromthe spool 43 onto the spool 47, the direction of the movement of theribbon may be reversed by actuating the switching devices 'so that theribbon may be again wound upon the spool 43. In order to effect thisreversal of the ribbon, the shaft 76 is rocked to an extent such thatthe finger 79 may operate upon and move the rod 7 0 and extension of thedog 74. In thus act ing the said finger moves the rod 70, which isflexible, toward the left against the pressure of the spring 2 until thepawl'69 is carried out of the teeth of the ratchet-wheel 68 and. thedepending portion of the dog 74 is vibrated sufficiently to carry saiddog down out of engagement with the teeth of said ratchetwhe'el, allafter the manner illustrated atthe left-hand side of Fig. 1. By the samemovement of said rock-shaft '76 the finger 78 is moved down and out ofcontact with the extension 67 and flexible rod til, and as soon as thistakes place the dog (36 rises to engagement with the ratchet-wheel 57,and the spring 6i, acting on the rod 61, operates to throw thedriving-pawl 58 into engagement with said ratchet-wheel, so thatthereafter said pawl may turn said ratchet-wheel and rotate the spool 43and wind the ribbon thereupon at each upward movement of said pawleffected by the rocker-arin G2 and rod 61 when the carriage is returnedto the right. The switch or rock-shaft 7G, with the fingers 7S and 79,is held in either of its two positions by a spring-detent S0, of anangular shape, to engage on either side of a pin 81 on said rockshaft.

From the above it will be seen that the ribbon is moved crosswise towardthe front of the machine as the carriage travels from right to left, andis moved crosswise toward the rear and simultaneously is fed lengthwisea short distance during the return of the carriage to the rightfor thebeginning of a new line. By referring to Fig. 5 these movements of theribbon will be found illustrated. The full or continuous lines representthe movements of the ribbon toward the front of the machine, while theoblique dotted or broken lines represent the movements of the ribbonlengthwise and crosswise on the return of the carriage to the right. 7

Referring to Fig. 6, it will be observed that the ratchet-wheel has itsteeth out in a direction opposite to that in which the teeth of theratchet-wheel 68 are out, so that the drivingpawl 69 may operate to turnthe ratchet-wheel and the spool and wind the ribbon on its downwarchstroke, instead of its upward stroke, as shown in Fig. 1, and where theteeth of the wheel 68 are thus constructed the teeth of theratchet-wheel 57 should be cut to correspond, or so out that the saidratchet-wheel and spool may be turned on the downward movement of thepawl 58. If the ratchet-wheels of the machine be constructed or arrangedso that the downward move ments of the driving-pawls 5S and 59 effectthe rotations of the said wheels, the ribbon will have movements such asrepresented at Fig. '7 of the drawings, the oblique full linesrepresenting the movements of the ribbon during the printing operationor during the travel of the carriage from right to left, and thevertical broken lines representing the rearward transverse movements ofthe ribbon during the return of the carriage to the right. In thisarrangement the ribbon is fed crosswise toward the front and alsolengthwise a short distance while the printing is taking place, and ismerely fed crosswise toward the rear when the carriage is pulled backfor the commencement of a new line.

By means of the cranks 42 the ribbon may be quickly wound by hand fromone spool onto another when it may be desired to remove the ribbon orput on a new one or bring a ribbon of a different color into use.

The ribbon-carriers preferably extend up to about the level at which theribbon travels horizontally across the machine, and ad j acent to eachribbon-spool carrier is arranged a shield or support 82, consisting of aplate of sheet metal attached to the top plate or typering and bent toextend inwardly over the type-bar hangers of the machine, thus shieldingthem from contact by the ribbon and at the same time affording adesirable support and guide for the ribbon.

I do not claim herein combining with the paper-carriage and its drivingpower a ribbon, a pair of ribbon-spools, and a transverse rock-shaftconnected to said spools and to the driving power, as suchsubject-matter is claimed in an application filed by me June -19, 1891,Serial No. 396,8l0.
